Enzyme catalysis is regulated by a number of mechanisms. Also, the flux through metabolic pathways must be regulated. Given the metabolic pathway below, which choice accurately describes the regulation of compound G levels?

#Section 2: General Biology
  1. G is regulated by chemical modification of the enzyme that catalyzes step 3.

  2. G serves as an inhibitory effector of the allosteric enzyme that catalyzes step 3.

  3. G inhibits the expression of the enzyme that catalyzes the formation of D.

  4. The reversible reaction of B to D is converted to an irreversible reaction.
